To Study the Effects of Refractive Surgery on OCT Measurements in the Eye

NCT05856786 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 33

Summary

Corrective eye surgeries, such as Lasik, are widely used to correct focusing problems such as myopia, or nearsightedness. Often these patients develop other conditions like myopic maculopathy or glaucoma which require monitoring with optical coherence tomography (OCT). Since OCT is a light-based test and changes the refractive status of the eye (in the cornea or the lens), it can potentially affect the results of the OCT measurements but has not been sufficiently studied. This pilot study aims at studying the potential change in OCT parameters in the eye after undergoing such surgery.

Conditions

  • Optical Coherence Tomography
  • Refractive Errors
  • Myopia

Interventions

DIAGNOSTIC_TEST

Optical coherence tomography

Posterior segment OCT (a non-contact procedure performed over one minute) is additionally performed for patients participating in this study. Proportion of change in measurements in microns will be analyzed.
